FS#1840 - Users to be able to change progress of ticket without editing

The way assigned users can comment and request task closure even if can't/don't edit the ticket, there should a js progress bar so they can adjust progress without editing it. When adjust progress, a comment box should popup (like what pops up when closing a task) so they can add a comment which would be attached to that change in progress.
